It’s always a bit difficult to test your webapplications in Internet Explorer if you are developing on Ubuntu. Your default test browser there will most likely be firefox.
But with with VirtualBox and Microsoft’s “Internet Explorer Application Compatibility VPC Image” it’s possible to test your website in a native IE6, IE7, IE8, IE9 and so on. Even on different platforms like Windows XP, Windows Vista or Windows 7!

It’s a bit hard to set it up, but let me show you how!

UPDATE: Testing IE with VirtualBox on linux has become easier with the xdissent ievms project!More >

Today the “/tmp” directory was full on a server because of a huge log file. When I checked it with the command “df -h” is saw that the directory used 100% of disk space. After I removed the log file, “df -h” still displayed the same value. I thought that it might be a caching problem, but the fact is that deleting a file name doesn’t actually delete the file.
It is not visible anymore if you execute the command “ls -sal”, but if some other process is holding the file open, it is not really deleted.
